The latest diet craze is nothing like the usual offerings. You don't have to count calories or even cut your food intake drastically. There's also no promise of instant weight loss, though you probably will become more trim.
What this diet will do is help prevent illnesses such as heart disease, Alzheimer's and possibly cancer, and significantly ease the pain of chronic conditions such as arthritis.
The 'anti-inflammatory' diet is based on the principle that many health problems are linked to chronic inflammation caused by an over-active immune system.
The theory is that certain foods help calm the immune system.
Those who have jumped on the bandwagon include Barry Sears, creator of the Zone diet, and dermatologist Dr Nicholas Perricone (the Perricone diet).
But what sets this latest trend apart from other dietary fads is the growing number of medical experts who agree there might be much to gain from it.
The idea that chronic inflammation can lead to ill health is well established. It occurs when the immune system begins attacking the body - it's not clear why this happens, but, as a result, the body tissues are damaged. In turn, they release chemicals that cause inflammation.
Because this initially causes no pain, people often don't realise they're suffering from chronic and 'silent' inflammation until years later - when the symptoms of arthritis or other conditions emerge.
